SH EATH FOR LEAD-PENCILS,

SPECIFICATION forming part of Letters Patent No. 345,364, dated July 13,1886.

Application filed February 17, 1885. Serial No. 156,202. (No model.)

To all whom it' may concern.-

Be it known that I, OTTO BUSSLER, of N uremberg, Bavaria, Germany, haveinvented a new and useful Sheath for Lead-Pencils, of

5 which the following is a specification.

This invention relates to sleeves or holders for lead-pencils, charcoal,and other material used for drawing and such like purposes.

In describing the invention reference will [0 be made to the drawings,in which Figure I is a half -elevation half -section, and Fig. II across-section.

In order to secure the lead,charcoal,or other material, 8, in theholders or sleeves with ad- 15 justable ring 1', the two halves, servingto hold the lead,&c., have hitherto been provided with corrugated edges,teeth, and similar devices, owing to which, however, the material wasdamaged without being completely secured in 20 the sleeve; or the entireinner surface of the cheeks has been lined with rubber.

The present invention consists in providing the spring-cheeks k with oneor more sockets, each of which holds a packing, e, of rubber or otherelastic substance, said pack- 2 5 ing being pressed against the object 8when the holder is tightened. These sockets formed on the inner surfaceof the cheeks hold the packing more securely andrequire less packingmaterial than the means hitherto adopted 0 for this purpose.

What I claim is- In holders for black-lead, charcoal, and similarmaterial, the combination of spring-cheeks is, having on their innersurface one or more 35 sockets, with elastic packing-pieces e fittedinto said sockets, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

OTTO BUSSLER.
